Configuration

Then, edit steemfeed_config.yml to configure. It has some items under Config category in the code.

  • discount: Discount rate (e.g. 0.10 means published price feed is 10% smaller than market price)
  • interval_init: Feed publishing interval in seconds
  • rand_level: Degree of randomness of interval
  • freq: Frequency of parsing trade history. Please be noticed that it can parse only 200 last trading history (Bittrex), so as trading is active you may need to decrease this frequency value.
  • min_change: Minimum price change percentage to publish feed
  • max_age: Maximum age of price feed
  • bts_ws : List of BitShares Websocket servers
  • witness: Enter YOUR WITNESS ID here
  • wif: Leave it empty. You will add your key with encryption when run the script first time
